Even the World's Deepest Trench is Full of Rubbish Now

The Mariana Trench is the deepest spot in the the world's oceans and it’s home to some strange sights, sounds, and creatures. But there’s one thing down there that’s very familiar: a whole bunch of rubbish.

At over 10,000 metres deep, the Mariana Trench is one of the most remote — and mysterious — places on Earth. We’ve only just begun to get a look at the unusual ocean life living down there, and what we’ve seen so far seems utterly alien. That makes finding out that is already heavily polluted all the more disappointing.

Earlier this month, University of Oxford researchers finally gave up on their quest to find a single still pristine spot anywhere on this Earth, saying that it simply didn’t believe one existed anymore. It looks like, even 10 kilometres below the seas, they were right.
